Embodiment 1
[0032] Embodiment 1: see figure 1 , the metal vacuum composite insulation panel is composed of shell 1, core material 2, core plate 3 and low-temperature solder 4, shell 1 is made of stainless steel plate, stainless steel plate, electro-tin plate, galvanized plate or aluminum plate with a thickness of 0.15-1.5mm It consists of thin metal plates such as alloy plates; the core material 2 is glass fiber, pearl sand, perlite, vermiculite, airgel, etc., and the core material 1 is preferably dried, packed in plastic bags, and pre-vacuumized; the core plate 3 It is a metal plate, a glass plate, a ceramic plate or a high temperature resistant polymer plate, preferably a tempered glass plate of 3-5 mm or an aluminum alloy plate of 1-2 mm. The manufacturing method of the metal vacuum composite insulation board is as follows: Firstly, two electroplated tinplates of the same size are cut out as the shell 1 to make the vacuum cavity, and the two electroplated tinplates are folded and forme...
Embodiment 2
[0033] Example 2: See Example 1 and figure 2, basically the same as Example 1, the difference is that the core board 3 is made of a high temperature resistant high polymer plastic board such as LCP board, which is directly placed in the vacuum chamber, and the metal plate forming the shell 1 is directly stamped out of the edge seal when stamping and forming The grooves used are used, and low-temperature metal solders such as tin, zinc, magnesium and their low-melting point alloys are placed in the grooves, and the airtight sealing of the vacuum chamber is completed by brazing in a vacuum furnace.
